Adafruit feather 8 channel servo driver. Moderators: adafruit_support_bill, adafruit

Hi

I've recently purchased an Adafruit feather 8 channel servo driver for a school project.

No matter what I tried, the 8-channel feather servo driver is not working for me. It shows up on an i2c scanner, but the servos either jitter slightly or are completely unable to move. This is using both a feather rp2040 and a feather huzzah 8266. Both of them run and compile the servo test code for the 8 channel i2c driver. I have tested controlling the servos directly via pwm, and they work flawlessly.

I can't figure out what I'm doing wrong. Please let me know if you have any suggestions in regards to this.

Many thanks

Post a photo showing your connections between the microcontroller and the Servo Driver and we'll take a look. 800x600 images usually work best.

The feather board is stacked underneath the servo driver. Power is supplied to the feather through USB and the servo driver gets power from a 3.3v 1200mah lipo battery

Thanks. What are you using as a power source for the servos?

A 3.3v 1200mah lithium ion battery.

You need a 5V power source for the servos:

Ok. I tried it with 5v and it worked! Thanks.

Gladd to hear that did the job. Happy hacking!
